The invention relates to improvements 4in 'pneumatic spraying devices, and particularaly in devices ada ted 4to spray paint. vThe primary o ject of the invention is to 5 providefa novel sprayingdevce which adapted to apply paints of-dilferent colors s imulta'neously'to a surface, to obtain a mot-4 tled color effecteuch asis frequently-desired on ceramic tile and other articles.

e 10 A more specific obiect'is to provide a novel paint s praylng device having means' for prol 'jecting a. plurality offindependent jets of paint -upon the surface to be painted. v

Another object is to provide a novel spraying device of the' above claracteru-'hich issimple and inexpensive in construction,- and which isadapted tobe applied to a wide va riety of uses.

Ancillaryobjec come apparent as the description proceeds.

It will be evident that I have provided an advantageous pneumatic spraying, device which is provided with means for projecting lural independent jets of aint, and

a t of wlich is therefore adapted to simultaneouslyv s ray'paints of different colors upon a sing e'surface. The device is simple and'inex pensive in construction, and will not easily or et out of-order. Int is well adapted for ap ying paint to ceramic tile where a mottled color ap arance is often desired, but it contemp ated that other uses may occur to those skllled in the art. I claim as my invention:

1. A s Vraying device having, in combinaa t base plate, l,a closed hollow casing mounted onl one end of said late, a plura ity of paint nozzles extending t rough said casing, each nozzle being threaded into the rear wall of said casing and having a restricted passage extending through the front wa-ll of said casing, said casin being formed in its front wall with means or dischargingI pressure iluid about said nozzles, a bracket secured to the other end of said plateand extending on opposite sides thereof, ai lurality of paint conduits rigidly mounte on said bracket at one side of said plate, a plurality of flexible conduits connecting said iirst mentioned conduits to said nozzles -and lying closely along said one side of said pl ate, means for pressing said flexlble conduits against 1,cse,oos

cut off the supply of paintto said plate to and a pressure fluid supply line said nozzles,

opening through said plate into said casingA and extending through said end bracket at the other side of said plate.

12. A spraying device havin tion, a base-plate, a closed mounted on one end of said late,

ollow 'casing a plurality of paint nozzles extending t rough said cas.

said casinghaving a plurality of presfluid discharge openings arranged about a bracket secured to 'the other ing, sure said nozzles, end of said sidesV thereo rigidly mounted on said bracket at. one side of said plate, a plurality of flexible conduits connecting saidfirst conduits tosaid late and extending on opposite a plurality of paint conduits nozzles-,fand lyingclosely along said one side means for pressing said flexilate to cut oi nozzles, and a surefluid discharge openings about the dis- -charge ends 'of said' nozzles, a bracket secured to andextending across the other end of said plate, a plurality of paint conduits supported by one end of said bracket andy connected to said nozzles, anda ressure iiuid line opening through said plate into said casing and supported by the other end of said bracket, said conduits andsaid line extending respectively along opposite `sides of said base.

In testimony whereof, I have hereunto aiixed my signature.
